Advice 1: What morphological features

Many have heard the term "morphological characteristics" the lessons of the Russian language. But not everyone knows that and applies it to biology. To understand which characteristics of living organisms should be attributed to morphological, we must first define the terms.

Morphological features of plants and animals

Let's start from the beginning. Science morphology studies the internal and external structure of living organisms or their groups (genera, species groups). There are external and internal morphological characteristics of living organisms. Internal morphology is the well-known anatomy. One should not confuse morphology with physiology, which deals with the study of the functions of certain organs or systems of animals or plants.

It seems, in the definition of morphology is no big deal. But behind the apparent simplicity lies a huge amount of information. Morphology of animals combines several Sciences: anatomy, histology, Cytology and embryology. Same thing with the morphology of plants. It is for a number of morphological characteristics, we can refer the animal to a particular species, genus or even detachment. This, for example, height, weight, color of hair and eyes, length and shape of the tail and other features of the structure.

To the morphological characteristics of plants include the shape and size of leaves, shape of stem, type of flower and fruit and the like.

The morphology of the person

Like any living object, man too is subject to the General laws of biology. And in anthropology (the science that studies the human) have a special section of human morphology. This science is tightly connected with the rasovedenie in the study of certain patterns of development and change of those or other features characteristic of different people. For example, the morphology of the person can explain what the skull of the Negro differs from the European or skull to reveal the regularities of changes of skin color and hair depending on the habitat groups of people. Returning to the morphological characteristics, we can say quite simply: it's how you look – your height, color of hair and eyes, skin tone and body Constitution.

The morphological features of the soil

There is a common classification of soils based on their morphological features. It is not surprising, because each type of soil can be described on the basis of its external signs. In this case, scientists are the Foundation of such morphological features as the structure, the capacity of the soil and of its separate horizons, color, structure, addition, tumors include. And since the processes occurring in the soil have a direct impact on all these signs, studying the morphology of the soil, you can learn a lot about its origins and history.

Advice 2: What is histology

From the curriculum everyone knows that is the subject of study Sciences such as anatomy and biology. The term "histology" in daily life have to face much less often, but histology is closely associated with both Sciences, it is no coincidence that it is called microscopic anatomy.

Instruction

1

The term "histology" is derived from two Greek words "histos" meaning tissue, and "logos" – word, knowledge. Thus, histology is the science that studies the evolution, development, structure and function of tissues of multicellular animals and humans. Many people mistakenly confuse this with the medical diagnosis.

2

Histology, for the most part, science is descriptive. Its objective is to give explanations to the changes occurring in various tissues under certain conditions, and to interpret the emerging features of tissue structure in the condition of normal or pathology. In addition to biology and anatomy, and histology are closely interwoven Cytology and embryology.

3

Allocate public and private histology, normal and pathological. General histology deals with the study of the structure and functions of body tissues in General, and section private histology is devoted to the study of tissue structure of individual organs. Normal histology examines tissues in a healthy organism. Pathological describes how certain diseases affect tissue structural changes. In the directions this science is also divided into descriptive, evolutionary, and comparative, experimental, and environmental.

4

The object of the study provide histologic thin tissue sections and individual cells, so the study of their structure is possible only with the aid of powerful optical instruments – microscopes.

5

Histological examination in the clinical setting is the study of tissue samples taken from the human body. Histological, or otherwise, pathomorphological examination is crucial in the diagnosis of malignant tumors and also one of the ways of assessing the effectiveness of drug treatment. It can be carried out quickly and according to plan. Material for histological examination are usually obtained in the process of endoscopic examination or biopsy that takes a small piece of tissue of a particular organ.

6

Conclusion histological examination issued by a specialist doctor – a pathologist or a morphologist and pathologist.
